Failed Drone Batteries: A Second Life After High-Power Usage

As drone enthusiasts, we all know the thrill of pushing our machines to the limit. But what happens when our batteries can no longer keep up with the demands of high-power applications? Before you toss those cells aside, consider this: failed drone batteries might just have a second life waiting for them.

A recent study by researchers at Oak Ridge National Laboratory and the Army Research Laboratory has shed light on the potential for repurposing lithium-ion batteries after they've been subjected to intense, eVTOL-like power demands. While their findings highlight the challenges of extending battery life under such conditions, they also open the door to exciting possibilities for battery recovery and reuse.

To grasp the significance of this research, it's important to understand the unique stresses placed on batteries in high-power applications like eVTOL (electric vertical takeoff and landing) vehicles. During critical maneuvers, these batteries are subjected to extreme discharge rates, far beyond what we typically see in electric vehicles or consumer electronics.

In the study, researchers simulated the takeoff step of an eVTOL flight profile by subjecting lithium-ion cells to a punishing 15C discharge pulse for 45 seconds. To put that in perspective, most electric vehicle batteries are tested at rates of 1C to 3C, reflecting normal driving conditions. The 15C pulse used here represents a drastic increase in power demand, pushing the batteries to their limits.

Under these conditions, the batteries were able to deliver consistent capacity for around 85 cycles before experiencing a severe drop-off. However, the real story lies in what happened next.

After subjecting the batteries to the high-power 15C pulse test, researchers then ran a low-rate (C/3) cycling test. Remarkably, the cells bounced back, achieving their original capacity and demonstrating good retention. This suggests that the capacity loss experienced after the high-rate test was not irreversible, and that the batteries' low-rate performance remained largely intact.

It's a finding that has significant implications for those of us in the drone community. While we may push our batteries to the brink in pursuit of performance, this research indicates that even "failed" high-power cells could have a useful second life in low-power applications.

Despite the challenges, the low-rate recovery phenomenon observed in this study opens up exciting possibilities for repurposing failed high-power batteries. While these cells may no longer be suitable for the rigorous demands of eVTOL or high-performance drone applications, they could find new life in less demanding roles.

Consider, for example, a drone battery that has lost its edge after one too many aggressive flights. While it may no longer have the punch required for acrobatic maneuvers or extended flight times, it could still serve admirably in a lower-power application. Perhaps it becomes the power source for a sensor array, a low-speed inspection drone, or an educational robotics project. The possibilities are vast.

Of course, repurposing batteries is not as simple as just plugging them into a new device. Careful consideration must be given to factors like capacity matching, battery management system compatibility, and safety considerations. But with the right approach, the potential for giving failed high-power batteries a second life is significant.
